Title: Microfiltration process and apparatus
Inventor: MUELLER WOLFGANG
IPC: C12H1/06
Filed: 1990-11-02
Abstract: The invention relates to a microfiltration process, in particular for separating beer from a materials flow which is purged during the fermentation process and which takes along the excess yeast produced during the fermentation, wherein the materials flow containing haze substances to be filtered is passed under pressure through at least one microfiltration module with porous membranes carrying a tangential flow and a filtrate is taken off. According to the invention, the materials flow to be filtered is continuously fed to a circulated retentate flow, and a concentrate flow having a substantially constant concentration of haze substances is taken off from the retentate flow. The flow velocity and the flow pressure drop of the retentate flow are measured and the concentration of haze substances in the retentate flow is determined from the measured data according to a function F (v,  DELTA p) which is characteristic of the apparatus and which contains the flow velocity (v) and the flow pressure drop ( DELTA p) as variables. The concentrate flow rate is controlled in accordance with the difference in the concentration of haze substances, resulting from a comparison of actual and set values.

The brake bleeder valve does not  have  to  be  re-tightened  in the bleeder valve recess between  each  downward stroke of the brake pedal to prevent leakage  of  hydraulic fluid and re-introduction of air into the lines during the interim between downward strokes.
Patent CA-2033697-A1 (CA)
Inventor: DASGUPTA PURNENDU K
IPC: G01N30/02
Filed: 1991-01-07
Abstract: A method and an apparatus for the generation of a high purity chromatography eluent are provided. In one form of the invention, an eluent generating means defines a source channel and a product channel separated by a permselective ion exchange membrane including exchangeable ions of the same charge as the selected ionic species. The membrane allows passage of ions of the same charge as the ionic species but is resistant to transmembrane passage of ions of opposite charge.      Means are provided for applying an electrical potential between the source channel and the product channel. The effluent from the product channel is directed to chromatographic separation means. Means are also provided for supplying liquid sample to the chromatographic separation means. By means of this system, only ions of the same charge as the selected ionic species flow across the ion exchange membrane into the product stream since the membrane is resistant to transmembrane passage of ions.      This eliminates oppositely charged ions that would otherwise interfere with the accurate analysis of the ionic constituents of the sample during ion chromatography.

Abstract: A method for optimizing the pacing and processing of inbound calls and outbound calls. Statistics are generated concerning inbound calls and outbound calls, and concerning the performance of each agent for inbound calls and outbound calls. Separate statistics concerning inbound calls and outbound calls allow a more accurate prediction of call pacing and handling requirements and of the availability of an agent so as to maximize the productivity of each agent and control the on-hold time of inbound and outbound calls.      Each trunk line is designated for inbound calls or outbound calls and the status of each trunk is monitored. If all of the trunks allocated to inbound service are in use then some of the trunks designated for outbound service are redesignated for inbound service. If more than a predetermined number of trunks designated for inbound service are not in use then some of these trunks will be redesignated for outbound service. Therefore, the rate of answering of inbound calls and the rate of placement of outbound calls, and the allocation of trunks between inbound calls and outbound calls are driven by the frequency, duration and number of calls and user-selectable options.

Title: Enhanced computer aided design system
Inventor: CHEN LIANGPIN
IPC: G06T15/00
Filed: 1991-11-14
Abstract: ABSTRACT      Disclosed herein is a design system for designing, dynamically changing and displaying design drawings.  The invention allows a user to select a solid object from a display as the current, active object.  The user then selects a first, parent face by selecting any point on a face of the solid object.  Next, the user is prompted to select another point on a line of another face parallel to the first face.  This operation defines the first offset face which is a variable distance from the first parent face. Subsequently, the user selects a point on a line to define a second parent face of the solid object.  Then, the user selects a point on a line parallel to the second parent face.  This defines the offset face and a corresponding distance between the two faces which is a fixed value. Finally, the user is prompted to enter a new distance between the first parent face and the first offset face.  This new value is used to generate a new solid based on a change to the variable distance between the first two faces and a corresponding shift in the location of the fixed distance between the second pair of faces and a resulting modification of the surface.
